Abstract

PURPOSE:To vary air compliance in linear form against to vibration amplitude, by employing a subordinate vibration diaphragm instead of using a damper. CONSTITUTION:The internal circumference of a subordinate vibration diaphragm 13 is stuck to the external circumference of a bobbin 4, and the external circumference is fitted to a main vibration diaphragm 8 through an elastic body 14, such as an edge, rubber and corrugation edge. Consequently, since the subordinate diaphragm 13 is harder than a conventional damper, strain originating from the vibrations of the bobbin 4 is reduced and the reduction of the area of the elastic body 14 makes the area of elasticity less than that of the conventional damper, lessening fatigue. Further, air compliance has linear characteristics to vibration amplitude.
